Phylum Rotifera Part 3: Subclade Acanthocephala (Parasitic Spiny-Headed Worms)

The video explores the acanthocephalans, a group of obligate endoparasites within the Rotifera phylum. It covers their classification, physical and physiological characteristics, including their unique proboscis and lacuna system. The video also details their nervous and reproductive systems, life cycle, and interactions with hosts. Human infections are rare, with specific species occasionally affecting humans. The study concludes with a transition to the phylum Molluska.
